The countTrue() method of Booleans Class in Guava Library is used to count the number of values that are true in the specified boolean values passed as the parameter.
Syntax:
public static int countTrue(boolean... values)
Parameters: This method accepts the boolean values among which the true values are to be count.
Return values: This method returns an integer value which is the count of values that are true.
Example-1 :
// Java code to show implementation of // Guava's Booleans.countTrue() method import com.google.common.primitives.Booleans;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a Boolean array
boolean [] arr = { false , true , false ,
true , true };
// Using Booleans.countTrue() method to
// get the number of values that are true
System.out.println(Booleans.countTrue(arr));
}
} |
Output:
3
Example 2 :
// Java code to show implementation of // Guava's Booleans.countTrue() method import com.google.common.primitives.Booleans;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a Boolean array
boolean [] arr = { false , false ,
false , false };
// Using Booleans.countTrue() method to
// get the number of values that are true
System.out.println(Booleans.countTrue(arr));
}

Output:
